Gasoline Vehicles, Transmission, Removing
Short Description
The transmission is remove downward by itself.
"From above" :
The battery, air filter housing and starter are removed. The steering gear wiring harness is disconnected and freed up. This way it can be lowered together with the subframe and steering gear. The engine and transmission are supported before the transmission mount bracket is removed.
"From underneath" :
The subframe, with the pendulum support, the steering gear and both lower control arms are removed together.
Both drive axles are disconnected from the transmission and remain inside the wheel bearing housings. Occasionally they will be moved to the side, but they still remain on the vehicle.
